I installed Ubuntu 12.10 on my new Windows 8 Dell Inspirin and would like to set up a Dual Boot. However, when I restarted, it just went straight to Windows 8 without giving me a Grub screen with options to start Ubuntu. I haven't had luck with EasyBCD or the BootRepair utility.

New computers which come with Windows 8 use UEFI, a try to replace the old BIOS firmware. You can read about this on Ubuntu wiki, but I'll paste you some things you can try to do.

Create a LiveDVD or LiveUSB of Ubuntu-Secure-Remix 64bit or of Ubuntu (>=12.10) 64bit. The former is more convenient, as it already includes Boot-Repair, which is used in step 4.

Boot your PC using the LiveDVD or LiveUSB and choose "Try Ubuntu". Remark: if you get a Secure boot or signature error, disable SecureBoot as described here, then retry to boot the disk. You may also need to disable QuickBoot in the same menu.
Install Ubuntu from the Live CD/DVD or Live USB in the usual manner, then reboot the PC.

If the PC does not load Ubuntu (but instead loads Windows, for example, as in Bug #1050940), or if the Windows entry in the GRUB 2 menu does not boot Windows (see Bug #1024383), boot your PC using the Live CD/DVD or Live USB and choose "Try Ubuntu" once again. When the live session has loaded, run Boot-Repair (see link for details). When Boot-Repair loads, click on the "Recommended repair" button, and write on a paper the URL (paste.ubuntu.com/XXXXXX/) that will appear.

This should fix most boot problems. If this does not fix your boot problems, please follow this procedure. If still not good, please create a new thread in this forum, describing your problem and indicating the URL you wrote in the previous step.
